Attribution
The method by which a payer or value-based program assigns each patient to a specific provider or organization accountable for that patient's cost and quality outcomes. Attribution rules determine which entity earns shared savings or bears performance risk.
What is attribution in value-based care?
Attribution is the method a payer or value-based program uses to assign each patient to the specific provider or organization considered accountable for that patient's cost and quality of care. Because patients often see many clinicians, attribution rules establish who is treated as responsible for the overall result.
These rules can be based on factors such as which provider delivered the most primary care visits or where the patient chose to enroll. The precise logic varies by program, and small differences in the rules can change which patients land in a given provider's panel.
Why does attribution matter for payers and providers?
Attribution determines who earns shared savings when costs come in low and quality stays high, and who bears the downside when performance falls short. As a result, it directly shapes the financial stakes a provider faces under a value-based contract.
It also defines the population a provider is measured against, so misattributed patients can distort both quality scores and cost benchmarks. Understanding and reconciling attribution lists is therefore an important part of succeeding under risk-based arrangements.
